MOTOR-VEHICLE.

Specification of Letters Patent.

Patented Nov. 12, 1.918.

Application filed January 10, 191e. Serial No. 71,266.

To all whom t may concern.'

Be it known that I, ALFRED NEWTON HAM- RICK, of Silt` in the county of Garfield and State of Colorado, have invented certain new and useful Imlnovcments .in Motor-Ve hiclcs; and I do hereby declare the follow ing to be a full, clear, and exact description of the invention, such as will enable others Skilled in the art to which it appertains to make and use the same.

My invention has reference to that claw of motor vehicles employing a dynamo and means for operating the same, the dynamo being adapted to generate electric energy or use in a motor which is normally adapted to rotate the traction axle. In ca rinsingr forward this broad idea I employ improved means by which the vehicle when being propelled forward by its own momentum. as When coasting down a hill. may operate the dynamo to store up energy. I also provide means by which the'elemeut normally or erating the dynamo. preferably a gas engine, may directly rotate the traction axle. I also provide means by which this engine may operate auxiliary to the motor and the two by independent connections rotate the traction axle.

In the accompanying drawing' the figure is a plan vien' of a` motor vehicle embodying my invention.

As illustrated` thc running gear rtnmm'iseh` forward wheels 1 and rear Wheels 2, the latter connected by a traction axle 3 on which is fixed an electric motor 4, the axle 3 being movable with the armature of the motor. I have shown an uccumulator in the form of a serios of storage batteries in electrical connection as at 6 with the motor 4, a rheostat 7 being located in the conductors. The storage batteries: derive their electric energy from a dynamo wthrough conductors 9 in which is interposed a switch 10. The dynamo is preferably operated by means of a gas engine 12, the shafts intermediate the dynamo and the engine, having a clutch 14 which may be operated by a bell cra ni( lever 15 on which is a pedal 16 within ready reach of the operator of the car.

Also on the armature of the dynamo I have shown a shaft 17 in operative relation to a. shaft 18, these stub shafts being connected by u clutch 19 operated by e bell crank lever 20 having a pedal 21.

The shaft le carries` a gear 2Q in mesh with a pinion on a Shaft 24, this shaft carrying at its free end a beveled gear 25 adapted to mesh with either one of a pair of gears 26, 2T keyed on the traction axle 3. These gears Q6., 2T may be shifted so that one or the other of them will he in mesh with the ,ejem- 25 or into the neutral position by Incom of a rod Q8 under the control of a lever 9 preferably arranged at the fno-ward Mnl of the ce? :wird Within. easy reach of the operator.

With tht parte arranged shown and described ihr encino l). may constitute the means for working the dynamo 8 to create electric energy'. the clutch 14 being closed. The electric ener-prv created by the dvnamo maiy llo lranomitted through conductors 9 and 6 to (he storage batteries 5 and the mo tor 4.-. This; may be termed the normal 0D- erating means. ,Mourning however that the vehicle in coasting and requires no traction power the rheoetat 7 may be turned to cul: out the motor 4, and the lever 29 shifted to bring one of the .floors 26 or 27 into engagement with gear 2F and the pedal 16 mav be operated 1o onen the clutch 14- thus discon-A necting the engine 'from the dynamo and the confine ninv he stunned, A, a result the rotation of the traction axle B and the cnaagemont o'lu one of ite gear@ with the Shaft 24 will rotate the pinion 23 and gear 22. and clutch 19 heine closed will result in oneratinor the dynamo to atore up energy in the batterieel Again, with the motor 4 rendered inettective the clutches 14 and 19 may remain cloned and the engine 1Q mov be onerated and ite direct function will be to rotate the traction axle through the described train of nearing. In this nosition o i nartsswitch l() mav be opened so that althonfrh the dvnamo operates' it will not be effective to store un energrv. r. manifeetlv. the motor 4 mav be maintained effective to rotate the traction axle and in this: pooition the flinction of the engine will be auxiliary to that of the motor.

I claim as mv invention:
